Bedienungs- und Installationsanleitung

Installation- and Operation Instruction

Meßgaskühler / Sample Gas Coolers PKE-42

3 Installation and Connection

The PKE-42 sample cooler is to be attached to vertical panels. The heat exchangers either made from

stainless steel, glass or PVDF are inserted from the top. Make sure, that there is enough space left above and

under the cooler to get the pipes/or hoses connected to the unit.

The place of installation must be weather shielded and air shall circulate freely around the cooler. The ambient

temperature shall not exceed the range from +5 to +50°C (+41 to +122°F) for the PKE-42.

Free air circulation must be provided. On both sides a gap of at least 10 cm (4 inches) must be kept clear.

Free air circulation must also be provided if the cooler is installed inside a cabinet. In some cases a fan is nec-

essary to establish sufficient circulation within the cabinet.

3.1 Mounting

Depending on the application parameters the connecting pipes or hoses must be of adequate material and

fastened tight. Connect the hoses to the heat exchangers made of duran glass with care to avoid breaking the

glass.

Make sure that all sample gas lines leading to the cooler are installed with downward slope to enable conden-

sate flow into the heat exchanger by gravity.

In some applications with very high condensate content separators upstream the cooler could become neces-

sary (see catalogue for appropriate types).

The gas entrance is marked with red.

If the sample gas pump is located upstream of the cooler, the condensate can be drained off by automatic

condensate drains. If the pump is located downstream peristaltic pumps or condensate vessels must be used

for removal (see our catalogue for appropriate equipment).

Important: The PVDF heat exchanger type DTV cannot be used with automatic drainers but with peristaltic

pumps only.

The condensate drains can be attached directly to such coolers with stainless steel heat exchangers. In case

of glass heat exchangers the condensate drains must be connected with flexible lines fixed with by brackets

separately.

The condensate lines must be installed with considerable slope and should not have less than 8 mm (0,3 inch)

inner diameter.

3.2 Electrical connection

WARNING

The device must be installed by trained staff only.

CAUTION

Wrong mains voltage may damage the device.

Regard the correct mains voltage as given on the type plate.

WARNING

Damage to the device in case of insulation testing

Do not proceed insulation tests with high voltage to the device as a whole.

The device is equipped with extensive EMC protection. If insulation tests are carried out the electronic filter

devices will be damaged. All necessary tests have been carried out for all concerned groups of components at

the factory (test voltage 1 kV or 1.5 kV respectively, depending on the device).

The device is equipped with connectors according to DIN 43650. After correct wiring the connectors cannot be

interchanged and must be wired according to the following diagram (numbering can be found on the connec-

tor). Make sure the connector is correctly refitted after wiring.

Mains voltage is 230 VAC 50/60 Hz or 115 VAC 50/60 Hz (regard type plate).

If the cooler is equipped with peristaltic pumps, they must be connected to a separate power supply.

Heat Exchanger

The energy content of the sample gas and, as a result, the required cooling capacity of the gas cooler is determined by 3 parameters: gas

temperature J , dewpoint t (moisture content) and flow v. The outlet dew point rises with increasing energy content (heat) of the gas. The

required cooling capacity is determined by the maximum acceptable level of the outlet dew point.

The following table shows cooler performance assuming the following conditions: t =120°F and J =160°F. Indicated is the v in lpm cooled

air (i.e. after the moisture has condensed).If the actual values stay below the parameters t and J , v can be increased. For example (TG),

instead of t = 120°F, J = 160°F and v = 5.7 lpm the values t =105°F, J =160°F a maximum flow rate of v=7.1 lpm could be achieved.
